Inspection Date: 10/30/2020 Inspection Type : Compliance Evaluation
Reason for Visit: Routine
Inspection Summary:
Staff of the Mooresville Regional Office (MRO) conducted a compliance inspection on October 30th, 2020. The MRO would
like to thank Mr. Lee Garner (ORC) for his time during the site inspection.
In general, the facility appeared well maintained and the treatment system to be operating sufficiently, however, the current
Water Level Indicator does not meet requirements under permit condition 111.13 and this item was noted for correction in the
previous two inspection reports.
Specifically, this Notice of Deficiency is for delay in installation of a Water Level Gauge with required increments. Item 111.13.
of your current permit states: "...This gauge shall have readily visible, permanent markings at inch or tenth of a foot
markings..."
The existing water level marker had a painted area to note the 2-feet of freeboard, but the paint is wearing off. Mr. Garner
discussed an option to install a floating dock as a safe way to attach a graduated marker to the existing one, and to provide
access for long-term maintenance. In addition, a floating dock is unlikely to damage the lagoon's clay bottom liner.
The MRO is aware there are safety concerns with installation, but recommends this be addressed before the next permit
renewal application is due, July 31 st, 2021.
The following additional maintenance items are noted so Reed Gold Mine may plan for and budget accordingly:
• The ORC discovered polyester fibers that caused blockage in the pumping system leading to a pump burnout in one
instance and a relay switch failure in another. The polyester fibers are from the lagoon berm design. Given the age of the
facility (approx. 30 yrs.) it is recommended the lagoon integrity be assessed by an Engineer in preparation for the next
permit renewal, as MRO staff will request this item be added as a permit condition.
• The septic tank and lagoon should be assessed for bottom residuals and pumped as necessary. Per on -site discussion,
the septic tank was only partially pumped when the backflow prevention was installed in 2015.
• The ORC noted some of the sprinkler head uprights are in need of repair/replacement for corrosion of the post at ground
level.
Please take the corrective actions for the above deficiency and maintenance items as necessary to bring the facility into
compliance. A plan and time -line for implementing corrective actions must be submitted in writing to the Mooresville
Regional Office by December 17th, 2020.
Should you have any questions, please contact Maria Schutte by phone at [phone] or email at
[e-mail].

Heavy solids are captured at septic tank and liquid is held in lagoon/polishing pond for at least 3(
days. Chlorination occurs prior to irrigation.

Comment: Monitoring wells appeared well maintained. Housing intact and locks in place at the time of
inspection. TDS is historically elevated in MW-2, may be geology for that well. Wells are not at
a compliance boundary, but appear to be located as best possible given topography and wet
soils beyond application fields.
